You've been corrupted by the narrative living in $ec country too long if you believe this. Starting next season they're the 2 best, sure, won't argue that as they've consolidated all the biggest teams. But any year prior to next season? The F they were the 2 best, the B1G in particular. Any given season they ended up just like every other conference with anywhere from 1-3 elite caliber teams, then roughly 1/3 to maybe half of all the remaining teams falling into one of 3 categories: solid to pretty good; mediocre at best; and garbage.In the AP era, they've also won six more football national championships than the remaining conferences and independents combined. They are the two best football conferences. If you just look at this century, the SEC is clearly the most dominant.
Alabama has been consistently dominant. OhSU has been as well. Please, for the love of God, stop the nonsense of letting those few schools' success overshadow the fact that the rest of the conference is populated by cannon fodder like Purdue, Illinois, Indiana, Vandy, Arky, South Carolina, etc... etc... etc...
